United States Patent ADHESIVE APPLYING ATTACHMENT FOR COLLATING MACHINES Application September is, 1952, Serial No. 310,272 2 Claims. c1. 118-221) This invention relates to an adhesive applying attachment, and one primarily particularly suitable for use in collating machines, in which manifold forms of various types are produced. e

In collating machines, of certain types, the strips of record sheets are fed from rolls and interleaved with transfer sheets in the forms of webs, all of the above taking place in timed relation, since the respective record sheets are ordinarily provided with printing upon the surfaces thereof. In order to carry out the collating of the respective record webs, it has been found desirable to suitably attach together at least the edges or an edge of the respective sheet, and likewise to provide for the fastening of the transfer web in position.

In providing for the fastening of the respective webs of transfer and record sheets, the desirable and simple way to dothe same is by means of adhesive and there fore the require'ment for a suitable attachment to apply the adhesive has arisen.

Further, in this regard it has been known that the application of adhesive is further desirably imparted in parallel rather relatively thin lines to the under surface of a web of record sheets whereby the same will adhere to the upper surface of a second web of record sheetsand a web of transfer material interleaved therebetween.

It is also well known that this collating takes place where a large number-even as many as or webs-are desirably fastened together so as to be infixed relation as the same pass through the machine, it being further desirable to apply the adhesive to the respective webs in parallel lines for the attachment together thereof. n

It is therefore a principal object of this invention, to provide a simple adhesive applying attachment which may be used with a collating machine of known construction; the same providing for the application of adhesive in the manner desired, and additionally being of such construction that it may be simply and readily cleaned. h a

It is a still further object of this invention to provide an adhesive applying attachment wherein the amount of adhesive delivered to its point of use may be varied within considerable limits, and yet excess adhesive will not be applied where not required.

It is a still further object of this invention to provide an adhesive applying attachment which may be arranged so as to supply a large quantity of adhesive without the requirement of refilling the same, and where refilling or supplying additional adhesive is concerned, the same may be accomplished with a minimum of waste and in a neat and non-spilling condition.

It is a still further object of this invention to provide an attachment which may be readily removed from its position in the collating machine, and quickly cleaned in order to prevent the accumulation of excessive adhesive which would dirty or otherwise spoil the material being collated in the machine.

Other and further objects of this invention will be understood from a consideration of the specification appended hereto, and shown in the drawings wherein:

Figure S is a side elevation view of the stripper shown in' Figure 4. e I I Figure 6 is a fragmentary perspective view showing the tubular outlet member for the supply vessel.

Referring now to Figure 1', the attachment is shown as comprising a body generally designated 1', the same being preferably in the form of a casting or other similar construction, and having depending therebeneath opposed flanges 2 and 3, whereby the device as a whole may be mounted on a collating machine, suitable mounting means being provided'in the machine, and set screws being adapted to be inserted in the openings provided a in the flanges 2 and 3, v

H The body 1 is of substantially rectangular configuration as indicated by the dotted line' forrnshown in Figure 2, including in one corner an outwardly extending section 4 of substantially circular configuration, the bottom of the body 1 denoted 5 being flat, and the bottom of the extension 4 lying in substantially the same plane as the bottom 5. e

The body 1 is further provided with relatively low upstanding sides 6 thereon, at opposite sides being fitted with bearing portions 7 and 8. The bearing portions 7 and 8 extend slightly above the edges of the sides 6, and mounted therein for rotation is a shaft 9, the shaft 9 being provided at one end with a drive member 10, whereby the same may be driven from the mechanism of the collating machine in any. preferred manner.

Suitably mounted on the shaft 9' and intermediate the ends thereof, is the adhesive carrier generally denoted 11, same being formed of a relatively thick disc, the ends of the same being parallel and denoted 12 and 13. The ends or faces 12 and 13 as previously mentioned being substantially parallel, terminate in the circumferential cylindrical portion denoted 14, and extending beyondthe circumference of the disc 11, are the flanges 15 and 16, the same being radially extending flanges and of relatively thin construction as shown in Figures 3 and 4. I

Further referring to Figures 1 to 3 inclusive, the body 1 is shown as supporting thereabove a table generally denoted 17, the same being fastened to the body 1 by means of a suitable wing nut and screw arrangement 18. This is provided in order to effect removal of the table 17 as desired. I The table 17 is formed of substantially L-shaped construction and includes a guide flange 19 at one edge, and a supporting flange 20 at the other edge thereof. Intermediate the flanges 19 and 20, are the additional supporting flanges 21 and 22, the latter being relatively closely spaced and between which the periphery of the disc 11 is adapted to' rotate. The flanges 15 and 16 of the disc 11, extend slightly above the flanges 21 and 22, for purposes which will be hereinafter set forth.

Rearwardly of the body 1, and supported on a shaft 23, the shaft 23 being connected to the body 1 by means of the screws 24 is the adhesive stripper and regulator member, generally designated 25, and clearly shown in Figures 4 and 5. This member 25 is-of substantially L-shaped construction, and includes the bearing portion 26 mounted on the shaft'23 and adapted to rock with relation thereto. At the lower end of the member 25, is an adjusting arrangement, consisting of a threaded shaft 27 in a suitable mating threaded opening in the member 25, and a knurled cylindrical nut 28 connected to the shaft 27. It will be apparent that by rotation of the nut 28, the shaft 27 will be moved inwardly and outwardly or as seen in Figure 5, from right to left, or vice versa. Rotation of the shaft 27 will cause the end thereof to contact the surface 29 of the body 1, and cause the member 25 to rock on the shaft 23 in a counterclockwise direction for example. Suitably provided in the upper arm 31 of the member 25, is a spring pressed plunger 30, which in turn contacts the upper edge of one of the sides 6 of the member 1, so that the member 25 is maintained in its adjusted position in conjunction with the pressure of the end of the shaft 27, in engagement with the body surface 29, wherever that may be within the limits provided by the adjusting arrangement 27.

Suitably fastened on the upper arm 31 of the member 25, is the part 32 being in the form of a strip having a body 33 fastened by the screws 33a to the upper surface of the member 31 and having an outwardly and somewhat slightly downwardly extending portion 34 formed as shown in Figure 4. The outer end of the portion 34 consists of the notches 35, between which a tongue 36 is thus provided, the tongues 37 and 38 being formed as shown, so as to extend along the ends or faces of the disc 11. It will be apparent that the notches 35 are spaced so as to correspond with the flanges 15 and 16 of the disc 11, and that the tongues 37 and 38 are closely spaced and substantially in rubbing contact with the ends or faces of the disc for purposes which will be set forth. Referring again to Figure 1, it will be noted that in this position the stripper and regulating member 25 is shown with the portion 34 in position adjacent the periphery of the member 11, and thus upon rotation of the member 11 by the shaft 9, a wiping effect results which prevents adhesive picked up during the rotation from the reservoir formed by the body 1, on the faces 12 and 13 from being carried above the surface of the table 17, and by suitable adjustment of the member 25, more or less adhesive may be carried on the peripheries of the respective flanges 15 and 16, in accordance with the requirements during operation of the machine in which this attachment is incorporated. Thus, by moving the member 28 in one or the other direction, the stripper and regulator unit 25 may be correspondingly moved, to raise and lower the end 34 to vary the distance between the ends of the notches 3S and the peripheries of the flanges 15 and 16 as will be apparent.

The supply means for adhesive will next be described, and consists preferably as shown in Figure 1, of a substantially cylindrical container 40, the same may be a glass jar or the like, having at its lower end suitable threads thereon by means of which the outlet member generally designated 41 may be fastened to the container 40. The outlet member 41 comprises a tubular member, shown in enlarged detail in Figure 6, as to its lower edge, and denoted 42. This tubular member is formed with a notch 43 in its lower end 44, which notch is in communication as shown in Figure 2 with the reservoir provided by the body 1. It will thus be understood that by suitably filling up the container 40 with adhesive, and properly manipulating the same into position with the edge or end 44 being supported on the bottom of the body 1 as in its extension 4, adhesive will be permitted to flow into the reservoir, but only so much adhesive as will be required to partially fill the reservoir and yet maintain the same in full condition.

In order to support the container 40 in its upright position and maintain the same therein a rod 45 is provided, seated in a socket 46 in the body 1, and at its upper end a bail 47 is engaged with the rod and surrounds the container 40.

In operation, the adhesive applying attachment of this invention, involves the rotation of the shaft 9 in the direction of the arrow indicated in Figure 1, and of course the disc 11 will thus be rotated likewise. The disc 1.1 will pick up adhesive in the reservoir provided by the body 1, and carry the same on its periphery upwardly. The tongues 37 and 38 on the outer edges of the member 34 being closely spaced with respect to the faces 12 and 13 of the disc 11, will scrape excess adhesive therefrom and the tongue 36 at its extremity will engage with the periphery 14 of the disc, to prevent the carrying of excess adhesive therearound. By suitably setting the stripping and regulating unit 25, the notches 35 will be suitably spaced from the periphery of the respective flanges on the disc 11, so as to permit a thin film of adhesive to be carried thereon. The adhesive will be transferred to a sheet of paper indicated in somewhat exaggregated fashion in Figure 3 at A, the same being a web or the like if used with a collating machine, and thereby parallel lines of adhesive will be applied to the under side of the strip A as the strip moves through the machine and over the table 17 from right to left as viewed in Figure l.

It will be apparent from the construction described herein, that the various elements of this attachment are simple and readily assembled so that cleaning of the same may be effected, and thereby prevent accumulation which would render the same faulty in operation and ineffective to carry out its purpose.

In order to prevent undesired rotation of the nut 28 by which the stripper and regulator unit 25 is adjusted, a suitable spring pressed plunger device 48 is provided, having a plunger 49 with a sharp end adapted to engage with the knurled portion of the nut. Thus the nut 28 will be maintained in its various adjusted positions.

We claim:

1. In an attachment of the class described, in combination, a body having an adhesive reservoir formed therein, an adhesive carrier mounted in said reservoir comprising a disc carried by a shaft having a narrow flange on the periphery thereof at each end, means for rotating the shaft, an adhesive stripper and regulator member pivotally supported on a shaft parallel to the first named shaft and including a stripper portion notched to receive the narrow flanges aforesaid and having a tongue closely spaced to each end of the disc, said memver further including settable adjusting means to maintain the stripper portion in a plurality of positions, and said member being slideable axially on said shaft, when the stripper portion is pivotally adjusted away from the flanges mentioned, and a table carried by the body mounted above the parts mentioned, provided with an opening through which a portion of the peripheries of the flanges described, may slightly extend, said table being removable as a unit from the body.

2. The combination as claimed in claim 1, wherein the table is provided with elongated parallel spacer means closely adjacent the portions of the flanges extending above the table for maintaining material to which adhesive is applied, in position with respect to the peripherics aforesaid.
